Electron impact excitation of krypton from the metastable state to the \(4p^{5}5p\) levels

  • Z B ChenEmail author


Using the fully relativistic distorted-wave method, we calculated electron impact excitation cross sections out of the two metastable levels of \(4p^{5}\)5sJ = 0 and J = 2 into the ten levels of the \(4p^{5}\)5p configuration of krypton. To obtain accurate results, careful consideration is given to the generation of the target state wave functions through the systematic inclusion of electron correlations. We find that the electron correlation has a large influence on the cross sections. This effect weakens as the incident electron energy increases. Our numerical results are compared with the available experimental data and other theoretical values over the measured energy range, showing a good quantitative agreement. We believe that these accurate results will be useful in plasma modeling studies.
